Analyze-Contain: Sentinel Mark V can use Outwit. Sentinel Mark V can use it normally, or Sentinel Mark V can use it targeting each opposing character with two action tokens that is within 10 squares and line of fire. You may counter a different power on each character.

Frigi-Beam: Sentinel Mark V can use Incapacitate. When it does and hits, choose one: a hit character can't be moved by any game effect until your next turn; or a hit character receives two action tokens.

See the Colossal Stamina and Great Size entries for more information.

When the Sentinel Mark V uses Frigi-Beam, does it place a token for using Incapacitate?
Yes. It uses Incapacitate (which includes placing a token on the target) AND it gets to choose one of those effects. Basically, you token the taget and prevent it from moving or you give the token two tokens.

With Frigi-Beam, one of the choices is to prevent the target from being moved by any game effect: does that prevent placement, too?
No. Movement and placement are two different concepts in Heroclix. Even though the target(s) of Frigi-Beam can't be moved if that option is chosen, they can still be placed.
